Dollar and Isaac pressure grain futures

Grain futures closed mixed on the Chicago Board of Trade Tuesday with the dollar index off 0.36 percent on the International Exchange. Corn was off 4 3/4 to off 5 1/4, soybeans were up 2 3/4 to up 8, wheat was off 1 to off 7 1/4 and oats were off 2 3/4 to off 5. Profit-taking continued in the corn market, as the U.S. Department of Agriculture said the harvest had just begun with less than 10 percent complete. Wheat futures hit a choppy day of trade that slid toward the close, following corn movement due to its value as a feed component. The soybean market remained on alert as Hurricane Isaac threatened southern growing areas. The prices: Corn: Sep 7.89 1/2 off 5, Dec 7.95 1/2 off 5 1/4, Mar 7.96 1/2 off 5, May 7.90 1/2 off 4 3/4.
